The expression 5(−2.3b − 4.1) − (7b + 0.7) can be simplified as follows:
= 5(-2.3b) - 5(4.1) - (7b) - (-0.7)
= -11.5b - 20.5 - 7b - (-0.7)
= -11.5b - 7b - 20.5 + 0.7
= -18.5b - 19.8
Therefore, the correct answer is −18.5b − 19.8.
= 5(-2.3b) - 5(4.1) - (7b) - (-0.7)
= -11.5b - 20.5 - 7b - (-0.7)
= -11.5b - 7b - 20.5 + 0.7
= -18.5b - 19.8
Therefore, the correct answer is −18.5b − 19.8.
